Description Troy Bernakevitch 2006-08-16 01:33:21 UTC

Description of problem:
Using via driver causes nothing but a blank screen to appear immediately after
RHGB. 

Version-Release number of selected component (if applicable):
0.2.1-4.1.i386

How reproducible:


Steps to Reproduce:
1.install fc6-t2
2.
3.
  
Actual results:
blank screen at boot

Expected results:
no blank screen

Additional info:
Hardware is a via K8M800 chipset, via pro graphics
The same machine was used for FC5 and via driver with no problems.
Changing to VESA driver will work, I also tried the xorg.conf from my FC5
install, but that didn't work.

I can provide additional info if needed

I'm seeing this as well on an MSI K8MM-V motherboard (the via K8M800 chipset is
integrated). When X is started, the screen goes blank and typing on the keyboard
has no effect. Booting to runlevel 3 works fine. Removing the xorg.conf file and
running system-config-display also blanks out the system. After ssh-ing in, I
can see the following logs:

This is with fc6t2 with all updates applied (the via driver version is the one
submitted by Troy).

Comment 2 Glen Basshem 2006-09-07 04:36:03 UTC

Xorg has fixed this bug in their code
https://bugs.freedesktop.org/show_bug.cgi?id=6668
It is the same as this bug
The patch attached to that bug report (6668) is not what thay implemented.
What was done is mentioned in comment #13, that is remove line 850 of via_dri.c
assert(saPriv)
I got xorg-x11-drv-via-0.2.1-4.1.src.rpm removed the line built it and installed
it on my machine. I have an ECS-K8M800-M2 motherboard with builtin unichome pro
video. It works fine.

Comment 3 Adam Jackson 2006-09-21 23:06:10 UTC

Fixed in 0.2.1-5.
